The shape of the skull in the first 18 months of life: findings from an MRI based morphometric study

The most widely accepted measurement in assessing the shape of the human skull is the cephalic index (CI). The current normal range is 0.73–0.81. The morphometric cranial changes in the first years of life are poorly understood. The aim of this study is to determine the change in CI in the first 18 months of life and see if it conforms to normality.
